 For fine-grained solids, the sensor must be aligned with the product

surface.

2.1.4 hints for in-tank effects

 Stirrers or agitators can cause a vortex. Mount the transmitter off-center

of any vortex to maximize the return echo.

 In non-linear tanks with rounded or conical bottoms, mount the

transmitter off-center. If needed, a perforated reflector plate can be

installed on the tank bottom directly under the transmitter center line

to ensure a satisfactory return echo.

 Avoid mounting the transmitter directly above pumps because the

transmitter will detect the pump casing as the liquid falls away.

 When install to the cold area, should choose the lengthen sensor of the

level meter ，make the sensor extend into the container, shun frost

and icing .
